Yeah maz, cigs on the ball and on point. I've been noticing this for quiet some time. On lots of gear. The dreaded
No Load. Back off too much and your res goes high, too tight and N/L until you hit the sweet spot and you finally get a good read from the chip. Love those grommets from Kanger. The firm ones are much better. But in reality its characteristic of the problem…the 510 connection.
The aero base as I wrote was long, long overdue in giving us a sealed connector. However, the drip continues unabated with every change of tank viscosity. And you know I've made a big deal about Nextel but its the only wick you can really clear out effectively of undue saturation. What's most deterred me from moving on to more sophisticated tanks is the horrible fear of not being able to clear the flooding caused by viscosity changes. Having to clear tanks by syringe or other means. There are advantages to Kanger clearo's. We now have a proper base.
So no what you and no doubt others are experiencing is absolutely normal even as I haven't written about it much.
To this I'll add that I've completed several long days of testing on the v2 now defunct single large hole aero base. It's a marvelous improvement. While it doesn't have quite the airflow of the original v1 bored out to 1/16" it seems to be better vectored so somewhat smoother. The thread finish is also much improved over v1 tank and base revisions.
The interesting thing in your example is that I've yet to experience any
No Load instances on any of my gear since installing these in use with PT2 and Aero tanks. The thread relationship (turn accuracy) seems to be tighter more well measured and uniform between heads and bases. I've yet to try any of the aftermarket PT2/3 universal assemblies yet. I have some just in. But the Kangers are quite good.
Now on to the v3 bases.
Good luck Maz.
p.s. Sharp brass tip on that PT.
